Description

  The present invention relates to a ventilation ridge disposed in an opening portion of a roof. In particular, it relates to a ventilation building that can cope with the difference in the slope of the roof.

There was a roof vent that could accommodate the slope. (For example, refer to Patent Document 1).
The prior art described in Patent Document 1 is provided with a baffle plate on one roof vent.
There was also prior art of a ventilation building that could cope with the gradient. (For example, see Patent Document 2)

Japanese Patent Laid-Open No. 7-3968 (first page, FIG. 1) Registered Utility Model No. 3005664 (first page, FIG. 1)

In the prior art described in Patent Document 1, one roof vent is bent and stacked on the roof. This roof vent was simply piled on the roof and fixed with screws, and its water-stopping property was low against rain and wind.
In addition, the prior art described in Patent Document 2 has an intermediate cover, so that the height of the ventilation building is increased and the appearance is poor. In addition, the baffle plate was formed to be inclined from the direction perpendicular to the inclination direction of the ventilation building. Since the mountain-shaped ventilation building itself inclined to both sides was deformed according to the gradient, there was a drawback that the air passage was narrowed when the magnitude of the gradient increased. That is, it cannot be used when the degree of gradient is relatively large or small.

An object of the present invention is to provide a ventilation building that can secure a ventilation path even if it is used corresponding to different slopes of a roof and can be used even if the degree of slope is relatively large or small. .
It is another object of the present invention to provide a ventilation building that can enhance water-stopping property to prevent rain and wind even when the degree of gradient increases, and that the height of the ventilation building is low and compact, and has a good appearance.

  The present invention is a ventilation mechanism comprising a ventilation mechanism that opens a field plate near the top of a mountain roof and discharges air inside the house, and a fixing member that installs the ventilation mechanism on the roof. It consists of an upper outer wall member, a lower outer wall member, and one or more blocking members. The blocking member is composed of a blocking plate and a cache plate, and the cache plates are located on both sides of the ventilation path formed in the ventilation mechanism. The barrier plate is formed in a direction perpendicular to the inclination direction of the outer wall member, and the fixing member reaches the roof plate contact surface parallel to the ventilation mechanism contact surface and is connected to the ventilation mechanism contact surface from one end of the roof plate contact surface. The ventilation building is characterized in that it has a connection surface and a ventilation mechanism fixing surface from the other end of the roof plate contact surface, and a water stop material is disposed on both contact surfaces.

  Moreover, it is preferable that a pair of fixing members is disposed on the left and right, and the connection surface of one fixing member and the connection surface of the other one fixing member are supported by a support member.

  Moreover, it is preferable that a ventilation mechanism consists of a crease pattern steel plate with uneven | corrugated shape continuing on the surface.

According to the first aspect of the present invention, even if the slope of the roof is relatively large or small, the air passage is not obstructed and ventilation can be performed efficiently. In addition, the ventilation mechanism does not have a conventional middle cover, has a compact form, and has a good appearance.
In addition, in a ventilation ridge that can be used by changing the inclination of the ventilation mechanism depending on the slope of the roof, rainwater is prevented from flowing into the room due to capillary action from a fixing member that fixes the ventilation mechanism and the ventilation ridge. be able to. Moreover, even when any inclination angle of the ventilation mechanism is changed in accordance with the gradient, the water-stopping material is disposed between the fixing member, the ventilation mechanism, and the roof, so that inflow of rainwater can be prevented. it can.

According to the second aspect of the present invention, by using the support member, the distance between the pair of fixing members arranged can be supported. In particular, the fixing member is screwed to the roof according to the gradient at the time of construction, but in such a case, the positioning of the fixing member can be facilitated. In addition, in a gradient-compatible ventilation building, a force is applied in the gradient inclination direction. It is possible to prevent the fixing member from changing its position in the gradient direction by the action of this force, and to prevent the pair of fixing members arranged in parallel from changing the direction and position.
In the conventional ventilation building, since there was no ventilation mechanism contact surface or connection surface in the fixing member, it was difficult to attach the support member. On the other hand, in the present invention described in claim 2, the fixing member has a ventilation mechanism contact surface and a coupling surface, and the ventilation mechanism contact surface is in contact with the ventilation mechanism via a water stop material. These can enhance the water stop effect. In particular, if the position of the fixing member changes due to the influence of outside wind or the like by supporting the fixing member by the support member, the air gap between the ventilation mechanism contact surface and the ventilation mechanism can be reduced. There will be no gaps and the water stop effect will not be lost.

According to the third aspect of the present invention, since the unevenness is continuous, the elastic water stop material between the ventilation mechanism and the blocking member is positioned by flexibly deforming the shape according to the concave surface or the convex surface. Become. Thereby, the water stop effect of a water stop material can be raised.
In addition, it is possible to prevent friction caused by the uneven shape between the ventilation mechanism and the blocking member, and the ventilation mechanism from being displaced from the fixed position due to external factors such as external wind.
In addition, the itch pattern with continuous irregularities gives an elegant appearance and has a great design effect.

The best mode for carrying out the ventilation building 1 of the present invention will be described.
1 is a perspective view showing an example of a ventilation building 1 according to the present invention, FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1, FIG. 3 is a cross-sectional view taken along the line AA in a state of being used on a roof having a small gradient, and FIG. It is an AA line sectional view of the state used for the roof with a large gradient.

  As shown in FIG. 1, the ventilation building 1 of the present invention is arranged at the top of a roof 2. The air behind the ceiling tends to accumulate hot air, and it is necessary to dry the room indoors by venting it to the outside. On the other hand, if rain and wind from the outside flows into the interior, the interior is corroded. Therefore, the ventilation building 1 is required to prevent the inflow of rain and wind while ventilating the interior.

  The roof 2 has various slopes. Conventionally, the ventilation building has been formed from a thin steel plate of about 0.35 to 0.4 mm, so it could be installed according to the gradient. That is, in the conventional ventilation building 91, as shown in FIG. When the ventilation building 91 was installed corresponding to the slope of the roof, the bending of the top portion 93 of the ventilation building 91 could be used by appropriately deforming it at the installation site.

However, the conventional ventilation building 91 can cope only with a narrower range than a normal gradient.
The reason is that the drainage 96 is installed on both sides of the opening 95 of the conventional ventilation building 91, but the water-stopping resin 97 is attached to the lower surface of the ventilation mechanism 92 so as to hit the upper part of the drainage 96, The inflow of water from the lower part of the ventilation building 91 was prevented. However, if the gradient becomes extremely large or small, the angle of the mountain-shaped ventilation mechanism 92 changes greatly, and the water-stopping resin 97 is not positioned above the drainage drain 96, so that the water-stopping effect cannot be obtained. It is. In order to cope with this, it is necessary to attach the water-stopping resin 97 in a wide range, but this requires a great deal of cost.
Moreover, the baffle plate 94 in the ventilation mechanism 92 is formed in the vertical direction regardless of the inclination angle of the ventilation mechanism 92. Accordingly, when the angle of the ventilation building 91 is changed, the interval between the plurality of baffle plates 94 is narrowed, and the air passage is narrowed. In particular, in order to prevent inflow of wind and rain, the baffle protruding from the top and bottom of the baffle 92 is inclined in the direction of inclination, for example, the baffle protruding from the bottom has a tip extending to about one fifth of the entire baffle protruding from the top. This is because the air passage was narrowed and the ventilation efficiency was not improved because it was formed long so as to overlap.
Therefore, in the present invention, even if the gradient is extremely large or small, it is possible to provide a ventilation building that can be installed without degrading the water stop effect while securing a ventilation path.

As shown in FIG. 2, the ventilation building 1 according to the present invention is configured such that a ventilation mechanism 5 that is hollow and has an air passage 4 formed therein is installed on a roof 2 by a fixing member 6. The top portion of the roof 2 is opened to be an opening 7. The roof 2 is composed of a roof tile 8 and a base plate 9, which are shifted and opened by about several centimeters in the inclination direction of the roof. A draining drain 10 is disposed on both sides of the opening 7.
The ventilation mechanism 5 is formed of a relatively thin steel plate having a thickness of about 0.35 to 0.4 mm. Therefore, as shown in FIG. 3 and FIG. Can be changed. That is, the inclination angle of the ventilation mechanism 5 can be changed according to the inclination angle of the roof 2 with the top 3 of the ventilation mechanism 5 as a fulcrum.

As shown in FIGS. 2 and 6, the fixing member 6 has a connection surface 13 in a direction perpendicular to the ventilation mechanism contact surface 11. There is a roof contact surface 12 in a direction perpendicular to the connecting surface 13. The ventilation mechanism contact surface 11 and the roof contact surface 12 are in parallel directions. There is a connecting surface 13 on one side of the roof contact surface 12, but there is a ventilation mechanism fixing surface 14 on the other side, a screw hole is opened, and the ventilation mechanism 5 is screwed. The ventilation mechanism contact surface 11 and the roof contact surface 12 have the foamed rubber material 16 disposed on the surfaces in contact with the ventilation mechanism 5 and the roof 2, respectively. When the ventilation building 1 is installed, a foamed rubber material 16 is interposed between the ventilation mechanism contact surface 11 and the ventilation mechanism 5 and between the roof contact surface 12 and the roof tile 8 as a waterproofing material. The foam rubber material 16 is preferably an EPDM material. This is because the EPBM material is a terpolymer of ethylene propylene diene, which is excellent in water-stopping, weather resistance, and heat resistance and is balanced. Thereby, it is possible to prevent rainwater from entering the opening 7 by the capillary phenomenon from the gap between the ventilation mechanism contact surface 11 and the ventilation mechanism 5 and between the roof contact surface 12 and the roof tile 8.
Moreover, by placing the foam rubber at the above position, it becomes possible to prevent rainwater from entering due to capillary action regardless of the inclination angle of the ventilation mechanism. There is no need to fill the gap with a water-stopping resin.

Further, the ventilation mechanism 5 and the blocking member, in particular, the second blocking member 21, are made of steel plates having unevenness on the surface and having a stagnation pattern. Concavities and convexities are continuous on the surface, and the disposed polyurethane water-stopping material 27 is also located in the recessed portion, so that it is possible to further prevent rainwater from entering due to capillary action.
In addition, the ventilation mechanism 5 having a stagnation pattern has a good appearance and has a visual effect that makes it look good.

As shown in FIG. 6, the support member 51 connects and supports a pair of fixing members 6 and 6 arranged on the left and right. The support member 51 is supported near both ends of the fixing members 6 and 6 in the longitudinal direction. The support member 51 includes inclined pieces 52 and 52 and contact pieces 53 and 53. The inclined pieces 52, 52 are bendable at the continuous contact 54. Thereby, the inclination angle of the inclined piece of the support member 51 is free according to the inclination angle of the roof.
The support member 51 supports the distance between the pair of fixing members 6 and 6 to be arranged at regular intervals. The contact pieces 53 and 53 are fixed and supported on the contact surface 13 of the fixing member. Double-sided tape is used for fixing, but a method such as screwing or rivet may be used. The contact piece 53 is formed in the vertical direction from the inclined piece 52.
The support member 51 can accurately support the distance between the fixed members arranged in a pair, and the pair of fixed members arranged in parallel can be prevented from changing its direction and position. If the position of the fixing member 6 changes due to the influence of outside wind or the like, it will take time for construction. It is preferable that a fixing member is disposed for easy construction. In particular, when the fixing member is supported by the supporting member and the position of the fixing member changes due to the influence of outside wind or the like, a gap or the like is generated between the ventilation mechanism contact surface and the ventilation mechanism to reduce the water stop effect. There is no end.

Next, the ventilation mechanism 5 will be described.
As shown in FIG. 5, the ventilation mechanism 5 includes a long upper outer wall member 31 and a lower outer wall member 41, and is formed by arranging a plurality of blocking members 20, 21, 22 between them. As shown in FIG. 7, the upper outer wall member 31 has a mountain-shaped upper inclined surface 32, and portions following the upper inclined surfaces 32, 32 are bent in a direction perpendicular to the inclined direction, 34. Two front surfaces 33, 33 are provided on the front side so as to be continuous with each of the upper inclined surfaces 32, 32 and the outer wall blocking surfaces 34, 34, and the two front surfaces 33, 33 overlap in the vicinity of the center. By forming the upper outer wall member 31 in this way, as shown in FIGS. 3 and 4, the inclination angle of the upper inclined surfaces 32 and 32 of the upper outer wall member 31 according to the gradient of the roof, with the top 3 as a fulcrum. Can be changed. In addition, although not shown in figure, the member used as a rear surface is provided in the opposite side to the front surface similarly to the front member.
The upper outer wall member 31 is hollow and the lower surface is also released. Long holes 35 and 35 are formed in the upper inclined surfaces 32 and 32, respectively. The long holes 35 are opened long along the inclined direction of the inclined surface.
This is a screw hole for locking the blocking member, and is appropriately opened to change the position of the blocking member according to the gradient to ensure a ventilation path.

As shown in FIG. 8, the lower outer wall member 41 has lower inclined surfaces 42 and 42 on both left and right sides when viewed from the front. Following each lower inclined surface 42, fixing member contact surfaces 43, 43 are provided in a vertically downward direction, and further, lower second inclined surfaces 44, 44 are provided following the fixing member contact surfaces 43, 43. Screw holes 45 are formed in the fixing member contact surfaces 43 and 43 and are fixed to the support members 51 and 51 with screws. Since the fixing member contact surfaces 43 and 43 are formed in the vertical direction, screwing is performed in the horizontal direction.
The lower outer wall member 41 has an air passage opening 46.

As shown in FIG. 5, the blocking members 20, 21, and 22 are fixed between the upper outer wall member 31 and the lower outer wall member 41. As shown in FIG. 9, the first blocking member 20 has a U-shaped shape having a fixing surface 23, a shielding plate 24, and an edge plate 25. As shown in FIG. 10, the second blocking member 21 has a fixed surface 23 and two shielding plates 24. As shown in FIG. 11, the third blocking member 22 has a fixed surface 23 and a shrimp plate 25.
As shown in FIG. 10, a polyurethane water-stopping material 27 is stuck on the fixed surface of the second blocking member 21 in particular. The water blocking material 27 uses a polyurethane material. By using an uneven steel plate with a concave / convex pattern for the ventilation mechanism 5 and disposing an elastic water stop material between the ventilation mechanism 5 and the second blocking wall, the ventilation mechanism and the ventilation mechanism of the blocking member are blocked. The water-stop material having elasticity between the members is positioned with its shape flexibly deformed according to the concave surface or the convex surface. Thereby, the water stop effect of a water stop material can be raised.

As shown in FIG. 5, the first blocking member 20 is fixed to the lower outer wall member 41 so that the caulking plate 25 comes to the opening 7 side. Fixing is done by rivets. The second blocking member 21 is screwed to the upper outer wall member 31 so that the caulking plate 25 protrudes in the direction of the lower outer wall member 41. The third blocking member 22 is rivet-fixed to the lower outer wall member 41 so that the caulking plate 25 is positioned on the discharge side from the opening 7 through the ventilation path 4.
Further, pedestals 61 are disposed at both ends of the ventilation mechanism 5. As shown in FIG. 12, the pedestal 61 has a round hole 62. Accordingly, as shown in FIG. 7, the base 61 and the second blocking plate 21 can be arranged at a predetermined position according to the gradient by the long hole 35 of the upper outer wall member 31, and the screw at the predetermined position of the roof gradient. Stop.

When the upper outer wall member 31, the lower outer wall member 41, and the blocking members 20, 21, and 22 are combined and fixed as described above, a hollow ventilation mechanism 5 is obtained. The hollow ventilation mechanism 5 has an air passage 4 formed therein. Since the shielding plate 24 of the blocking members 20, 21 is attached in a direction perpendicular to the fixed surface 23, the shielding plate 24 is positioned in a direction perpendicular to the inclination direction of the ventilation mechanism 5 in the ventilation path. Become. Since the shielding plate 24 is positioned in such a vertical direction, as shown in FIGS. 3 and 4, even if the ventilation mechanism 5 is attached in accordance with the gradient, the ventilation path 4 is not narrowed.
As shown in FIG. 5, the caulking plate 25 is not perpendicular to the direction of inclination of the ventilation mechanism 5, but is inclined toward the discharge side of the shielding plate from the vertical direction, so that the air passage 4 is not narrowed.

As shown in FIG. 5, according to the ventilation mechanism 5 formed by combining the upper outer wall member 31, the lower outer wall member 41, and the blocking members 20, 21, 22, air discharged from the indoor The air enters the air passage 4 from the air passage opening 46 of the member 41, and is discharged to the outside through the air passage 4. On the other hand, outdoor wind and rain is blocked by the outer wall blocking surface 34 and the shielding plate 24, and there is no risk of entering the indoor through the opening 7.
When the ventilation mechanism 5 is formed in combination as described above, the shielding plate 24 protrudes from above and below in the ventilation path 4. When viewed from the inclination direction of the ventilation mechanism 5, the shielding plates 24 protruding from the top and the bottom overlap each other by about 1 mm. This is because ventilation can be smoothly performed while preventing rain and wind from entering from outside.
